We look at the division of 15819029 by 205 
We're looking to find how many times 205 goes into 15819029.

Step 1:
If we divide 1 by 205, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 205

On to step 2:
15 divided by 205 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 205

Going ahead to step 3:
205 goes into 158 0 times with a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 158 and we're left with 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 205

On to step 4:
205 can be fit into 1581 7 times, resulting in a remainder of 146.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 1435 from 1581 and we're left with 146.
Append the next digit (9) from the dividend to 146 and continue with: 1469 / 205

Moving on to step 5:
When dividing 1469 by 205, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 77.0
The remainder is 34 after subtracting 1435 from 1469.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 205

On to step 6:
If we divide 340 by 205, we get 1 and a remainder of 135.
The next digit of our result is 1. 
Result so far: 771.0
Deduct 205 from 340 and we're left with 135.
Append the next digit (2) from the dividend to 135 and continue with: 1352 / 205

Advancing to step 7:
205 can be fit into 1352 6 times, resulting in a remainder of 122.
Record the quotient 6 as the next digit in the result. 
Result so far: 7716.0
Subtracting 1230 from 1352 leaves us with 122.
Append the next digit (9) from the dividend to 122 and continue with: 1229 / 205

Advancing to step 8:
If we divide 1229 by 205, we get 5 and a remainder of 204.
Write down 5 as next digit of the result. 
Result so far: 77165.0
Subtract 1025 from 1229 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 9:
The number 205 fits into 2040 9 times, leaving a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 77165.9
If we subtract 1845 from 2040, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 10:
1950 divided by 205 is 9 with a remainder of 105.
Record the quotient 9 as the next digit in the result. 
Result so far: 77165.99
Subtract 1845 from 1950 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 77165.99 with a remaining 0.105.
